If the number of available servers falls below the failover threshold in all clusters associated with the agent, policy operations do not stop. Requests are sent to the first cluster in the cluster sequence that has at least one available server.
For example, suppose an agent is associated with two clusters—C1 containing three servers, and C2 containing five servers.The failover threshold for any cluster associated with the agent is set at 60 percent.
The following table shows the minimum number of servers that must be available within each cluster:

If the number of available servers falls below the threshold in each cluster, so that C1 has no available servers and C2 has just two, the next incoming request will be dispatched to a C2 server with the best response time. After at least two of the three C1 servers are repaired, subsequent requests are load-balanced among the available C1 servers.
